Traditional methods for determining crash responsibility may not be accurate since issuance may vary by factors that are independent of fault, such as age and gender. These methods also do not capture driver behaviors that, while not unlawful, are still indicative of fault. An alternative method based on identifying crash-contributing driver actions should be used instead.

Crash involvement of an estimated 1,624 intermediate drivers was prevented in the first year after the NJ GDL decal's implementation, as well as a 9% decrease in the rate of police-reported crashes among intermediate drivers and a 14% increase in GDL-related citations issued to intermediate drivers. States considering implementing decals can look to NJ’s experience to shape their strategies.
